Celeb trainer Clay Burwell from High Performance NYC concocted an intense circuit for GL. Repeat it three times, twice a week.

Superman Lat Pull
Wrap a resistance band (snag one at Target) around the base of something sturdy, like a tree or the leg of a solid table. Get in a plank position, keeping your body stick-straight. Extend one arm and grab both handles in one hand. Bend your elbow and pull back. Slowly return to start. Do 20 reps and change sides.

Shadow Boxing
Gen a fight stance with feet about hip-width apart and one foot slightly in front of the other. Tighten your abs and make fists. Bend your knees to get a bit of a bounce going and practice punching (go to girlslife.com for ideas). Repeat for a couple minutes after each exercise.

Inchworm
Start with your hands stretched in the air. Reach for the ground and place your palms down. Walk hands out. You’ll hit push-up position along the way, but extend your hands farther out. Walk your legs up to your hands (it’s OK to bed your knees). Aim to “inch” for 40 feet.

Star Pushup
Start in a push-up position. Lower yourself and push up. Rotate your hips and torso to one side, while reaching the top arm up. Your feet will stack on top of each other as you rotate. Slowly lower back to start. Repeat on the opposite side. Start with two or three.

Side Kick

Start with your feet hip-width apart and your left arm bent under your chin with your hand in a fist. With your right hand, hold onto something sturdy (like a table). Lean to the right and bend your left knee. Kick your leg out, keeping your foot flexed. Repeat 10 times on each side.

Single Leg Squat
Start with your hands on your hips with feet hip-width apart. Bend your left knee, so your food lifts off the ground. Lower down, bending deeply on your right leg. Your left foot will touch down lightly in front of your right. Keep your back straight. Repeat 5 times on each side.
